Drew, a lot of the butterfly stuff was animated or composited. Also, their story of a specific butterfly was a bit of poetic license. They used shots of a butterfly in a storm and made it into an individual story. Thank heavens they didn’t try to track an individual butterly over the Atlantic when the country is $13 trillion in debt.

The information about salmon is indeed factual. The salmon morph into parr within several months after hatching and remain that way for sometimes as long as four years or more. Then they turn into smolt and leave the river. They are not technically mature(able to reproduce) until they return many years later. Furthermore the link provided by Sarah does not dispute this other than saying the par stage lasts only 3 years (which is usually but not absolutely true). I suggest you listen more closely to the wording in the video. Also whenever you want to dispute a scientific fact the ONLY appropriate sources are peer reviewed literature and data managed by organizations like NOAA. Websites that are trying to sell salmon are spurious at best.
